▎ 摘　　要

NOVELTY - Preparing the photo-thermal adsorption heavy oil material based on modified melamine sponge comprises (i) ultrasonically dispersing graphite oxide in water, preparing to obtain graphene oxide dispersion liquid, (ii) cleaning and drying the melamine sponge, (iii) dipping the melamine sponge in the step (ii) into the graphene oxide dispersion liquid obtained in the step (1), fully dipping uniformly, drying to obtain the complex sponge (iv) treating the obtained complex sponge in an inert atmosphere at a temperature of 200-600℃ for 1-60 minutes, wrapping graphene on the melamine sponge skeleton to obtain a three-dimensional porous material with high photothermal adsorption performance. USE - The method is useful for preparing photo-thermal adsorption heavy oil material based on modified melamine sponge, which is useful in oil product adsorption. ADVANTAGE - The method achieves fast adsorption, but also can be reused, and has broad application prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for photothermal adsorption heavy oil material based on modified melamine sponge prepared by the method.
